Goffin isn't an option, he's in the Newcomer Award poll though. And Matosevic is 27 and has been a pro since 2003 so he really isn't a newcomer. Chardy wouldn't be a comeback player too because he never really got injured, but rather he just slipped a bit down the rankings and came back up.

Tipsarevic would be an unusual pick for most improved, considering he finished 2011 ranked #9 and is still ranked #9. Normally people winning this award have bettered their ranking quite significantly.
